FLAME APPEARANCE

Flames from the pilot, front and rear burner should be visually checked as soon as the heater is installed.

In addition, periodically check the flames visually during operation.

CHECKING THE PILOT FLAME

The pilot ﬂame must always be present when the heater is in operation. It should just touch the top of the thermo- couple tip for natural. See Figure 27 for correct pilot flame.

If the pilot flame does not touch the thermocouple, then the main burner cannot function reliably. See Figure 28 for in- correct shape of pilot flame.
